Abstract

Dans un procédé de fourniture de secours d'un gaz sous pression par vaporisation d'un liquide pressurisé, ce gaz étant normalement fourni par vaporisation de liquide dans un premier échangeur (1) d'un appareil de séparation d'air à pompe, lors de la mise en marche d'un deuxième échangeur (2) pour produire le gaz d'appoint, du liquide pressurisé (33) et de l'air haute pression (8) continuent à être envoyés au premier échangeur.
